ClGAR-BUNCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 590,180, datedSeptember 14, 1897'. Application filed 0 ct0ber21,1896. Serial No,609,599. (No model.)

To (LZZ w/wm to may COILcQ/"H Be it known that I, WILLIAM YELLOWLEY,acitizen of the United States, residing at Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Oigar-Bunching Machines; and I do declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the .art to which it appertains tomake and use the same, reference being had to the accompanying drawings,and to the letters of reference marked thereon, which form a part ofthis specification.

My invention relates to cigar-bunching inachines; and it consists incertain improvements in the machine patented to myself and Charles Meyeron June 30, 1896, No. 563,115.

My improvements relate to the mechanism for actuating the rams, to theautomatic stopmotion, to the construction of the rams themselves, to therollingapron, to the moldboardracks,- and to the guide-rollers for thefeeding-rings.

In the drawings,- Figure l is a side elevation of my improved machine,certain portions being shown in section. Fig. 2 is an enlarged View ofthe stop-motion. Fig.. 2 is a detail. Fig. 3 is a detail showing theclutch. Fig. at is the front elevation of the lower end of a ram. Fig. 5is a plan and end view of the movable sections of the ram. Fig. 6 is aside elevation of one of the iollingtables. Fig. '7 is a perspectiveview of the same. Fig. 8 shows one of the adjustable mold-racks, andFig. 9 is a section showing the adjustable guide-rollers.

The principal parts of the machine are the same as those in the patentabove referred to-that is, the frame A carries a flat table B, on whichare supported the concentric feeding-rings O, movable under guides D.The feeding-pawls are actuated by a lever E. The main shaft F has apinion f, meshing with the gear-wheel G, which carries the grooved diskor cam H, by means of which the radiusarms I are vibrated to operate thebunchingrollers I. The rains K are vertically movable and serve to forcethe charges of tobacco from between the feeding-rings into therollingapron.

One of my improvements consists in the mechanism. for actuating therams, as shown in Fig. 1. I dispense with the triangular cross-headshown in the patent mentioned and in place of it I provide two levers L,fulcrumed at Z on a bracket (1 and having their outer ends slotted toengage with pins in the lower ends of the plungers it, to which the ramsare attached. The levers L are 0011- nected by links Z with rock-arms L,fulcrumed at Z on brackets a and having their inner ends connected by apin and slot, so as to permit vertical movement, The pin is engaged bythe cam H, and in this way the cam is enabled to impart a Vibratorymovement to the levers L to actuate the rams.

Another and an importantimprovement is the stop-motion. (Shown in Figs 2and 3.) One of the radius-arms I on one side of the machine is providedwith an extension or elbow 1 in which is a curved slot i, concentriowith the pivot t" of the radius-arms. Near the middle the, slot iswidened, forming a notch t on one side. The treadle M, which operatesthe clutch m, has a rod N hinged to it at n and carrying at its upperend a pin or roller 72, engaging with the slott'. The rod is adjustablein length, as by means of a turnbuckle n Means are providedto keep thepin or roller 01 pressed yieldingly toward that side of the slot iopposite to the notch F. This may be a helical spring 0, fastened at oneend to the frame A and at the other to the rod N, as shown.

The two treadles M are both pivoted to a clevis P, which passes througha stationary bracket R, and anelbow-lever M, fulcrumed thereon. Nuts 19secure the clevis to the elbow-lever, and a helical spring m, seated insockets in the bracket R and elbow-lever M, tends to lift theelbow-lever, the clevis, and the treadles. The upper end of theelbowlever is forked to engage with the movable portion of the clutch m,as clearly shown in Fig. 3. closed until pressure on either one of thetreadles opens it. 1

The stop-motion operates as follows: After the charge has been rolledand the radiusarms I are returning to an upright position they reach apoint (see dotted lines 90 in Fig. 2) where the notch '6 engages withthe pin or roller n and begins to push down upon the The spring tends tohold the clutch rod N. This movement continues until the radius-armshave reached the limit of their upward throw, (see position y in Fig.2,) at which time the treadle M will have been forced down to thedotted-line position in Fig. 2 and the spring 0 will have been put undertension, as clearly indicated. This depressin g of the treadle opens theclutch m and stops the machine, giving the operator time to remove therolled bunch and to place a fresh binder on the rolling-apron. 'Thishaving been done a slight pressure of the foot upon the treadle pullsthe pin or roller 01 down out of the notch 6 when the spring 0 at oncedraws the rod toward the frame A and keeps the pin or roller it awayfrom the notch, while the spring m closes the clutch and lifts thetreadle, the pin or roller 71 riding up the slot 2'. Upon the closing ofthe clutch the machine starts and another bunch is rolled.

Inasmuch as the space between the feedingrings is curved,- while thegroove in the rollin g-table which receives the charge is straight, Ihave provided the ram K with a head made in two parts and 70 eachadapted to move laterallyas, for instance, by being jointed together ator-near the middle of the ram by a bolt 70 which is secured by a nut 7&resting in an opening cut in the ram. The parts 70 k are thus free toturn on the bolt in a direction transverse to the line of movement ofthe ram. When the ram descends, these parts are swung into the positionshown in full lines in Fig. 5 by coming in contact with the Walls of thegroove in the rolling-table. When the ram rises, the parts are returnedto their original dotted-line position by reason of the curved shape ofthe slot in the table 13, through which the ram plays. To facilitatetheir return movement, I prefer to bevel or chainfer off the upper outercorners of the parts 7c as shown at 70 The rolling-apron S is attachedat its outer end to the rolling-table S. The apron passes loosely overthe roller 1, and in the patent above mentioned is firmly attached tothe socket S which supports the table S. I have found it desirable,however, to be able to roll bunches of different sizes, and in order toaccomplish this with the same table and apron I provide its inner endwith an adjustable fastening. The one I prefer is shown in Figs. (3 and7. The apron passes through a slot in the horizontal flange t of a metalplate T, secured to the rear of the socket S To the end of the apron isattached a weight U, preferably T-shaped, the stem of the T beingslotted to receive a stud V, which projects from the socket and isvertically adjustable in a vertical slot therein. A pin r in the outerend of the stud retains the weight U in place. The slot in the weightallows the apron to be pulled up by the action of the bunchingroller,and the position of the stud V determines the amount of slack in theapron. IVhen a smaller hunch is to be rolled, the stud is lowered, and,vice versa, it is raised when more slack is required for a larger bunch.In every case the weight U keeps the apron taut and insures a good tightbunch. The range of movement of the rollers I can be varied also bymeans of the slots 1' which afford an adjustable connection of theradiusarms with their operating-levers 1 My moldboard-support is shownin Figs. 1 and S. It consists of an arm \V, secured to the frame of themachine near the ram, and having an inclined sleeve 20. A rod WV passesthrough the sleeve and is adjustable lengthwise therein by means ofaset-screw w. At each end of the rod is a bracket V adjustable on therod by means of set-screws 10*. The brackets are adapted to receive andhold the moldboards X, as shown.

In order to provide for better adjustment of the feeding-rings G andalso to take up wear, I arrange guide-rollers Y inside and outside ofthe rings, mounted to rotate on stationary studs 1 which have stems yeccentric to the studs. These stems pass through the table B and aresecured by nuts 3 This construction enables the studs to be set in orout to adjust the position of the rings 0 and to take up Wear.

The machine may be provided with shelves for holding the binders,onenear each rollingtable, as indicated by dotted lines in Fig. 1 at Z.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is
